UNITEDv STATES PATENT OFFICE.

EZRA SMYTH, OF GREENCASTLE, INDIANA.

WRECKING-FROG.

SPECIFICATION forming'- part of Letters Patent No. 681,349, dated August27, 1901.

Application iiled April 30, 1901. Serial No. 58,159. (No model.)

To all wiz/0772, it may concern,.-

Be it known that I, EzRA SMYTH, a citizen of the United States, residingat Greencastle, in the county of Putnam and State of Indiana, haveinvented certain new and useful Improvements in Wrecking-Frogs; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to wrecking-frogs, and has for its object toprovide a device of this class which is adapted to be used to replacecars upon the track after the same have by wreck or other cause beenderailed.

A further object of my invention is to provide a wrecking-frog which canbe easily and quickly set up under a car and which does not require anydigging or otherwise disturbing the road-bed of the tracks.

A further object of my invention is to provide a wrecking-frog lwhichwill under all circumstances and conditions be held securely and rmly inplace and which will not yield and slide under the weight of therollingstock.

A further object of my invention is to provide a wrecking-frog which isso constructed that a car or engine which has not been derailed cansafely pass over said frogwithout being derailed.

A further object of my invention is to provide a wrecking-frog which issimple in its construction, positive in its action, and come posed of aminimum number of parts.

With all these objects in View my inven= tion consists in the novelconstruction, arrangement, and combination of parts, which will behereinafter fully described and afterward speciiicall y pointed out inthe appended claims. p

Referring to the accompanying drawings, Figure l is a plan view of mywrecking-frogs in an operative position. Fig. 2 is a side elevation ofthe outside frog. Fig. 3 is a crosssection through the same.

` Like numerals of reference indicate the saine parts throughout theseveral figures.

l represents the rails, and 2 the cross-ties.

3 is the outside wrecking-frog, composed of the horizontal platform 4,the vertical wall 5, the oblique vertical wall 6, and the inclined plane7. Said horizontal platform extends over and rests upon the rail 1.Secured on top of said platform and extending some distance in front ofthe same is an inclined rib 8, tapering toward its rear. Secured to theinner side of said horizontal platform and to the said inclined rib is avertical flange or Wall 9, which engages the inner side of the rail l.Secured on the top of said horizontal platform is a triangular plate 10,having a rearwardly and downwardly projection 11, said projectionresting irlnly on the rail 1.

Secured on the face of the inclined plane 7 are three arched ribs 12,13, and 14, the inner rib l2 having one perpendicular side and onecurved side, the central rib 13 being vcurved or rounded on both sides,substantially forming a semi-ellipse in cross-section. The outer rib 14.is curved. on its inner side, the outer side of which is secured to theoblique vertical wall 6.

Secured in any substantial manner to the under side of the horizontalplatform is a movable vertical plate 15, which is adapted to rest uponthe base or foot of the rail and which is connected in anysuitablemanner to threaded bolts,which are provided with handwheels or nuts, sothat the same may be securely adjusted.

Along the bottom edge of the vertical wall 5 and the forward edge of theinclined plane 7 I provide a series of spurs 17, which are adapted to beburied into the cross-ties by the weight of the rolling-stock, thussecurely holding the Wrecking-frogs from any longitudinal or lateralmovement.

Referring now to the inside frog 18, it will be observed that in generalform and construction it closely resembles the outside frog 3, with theexception that the rib 19 is not tapered and is beveled and inclined atboth ends, while the triangular plate 20 does not extend to and over therail.

The object of the inclined plane and arched ribs is obvious, and it willbe seen that when my wrecking-frogs are in position a car can safelypass over same without danger of derailment on account of the inclinedribs S and 19. Furthermore, it is my intention to join the two frogs byany suitable means, should I so desire.

Having thus described my invention, I do not Wish to be understood aslimiting myself to the exact construction as herein set forth, asvarious slight changes might be made therein by those skilled in the artwhich would fall within the limit and scope of my invention, and Iconsider myself entitled to all such changes and modifications.

What I claim as new, and desire to secure by Letters Patent of theUnited States, is-

l. In a railing device for rolling-stock for railroads, the combinationof an outside Wrecking-frog, an inclined plane, a series of ribssecuredthereon, a tapered inclined rib adapted to rest upon the top of the'rail, an inside Wrecking-frog on inclined plane, a series of ribssecured thereon, a rib inclined at both ends adapted to rest on top ofthe rail parallel with said rail, and independent from said ribs on theinclined plane and considerably above the same, spurs on the under sideof said frogs, a vertical Wall engaging one 1Q side of the rail, amovable plate engaging the other side thereof, and means for adjustingsaid plate substantially as described.

2. In a wrecking-frog, the combination of the horizontal platformextending from the top of the rail an inclined plane formed thereto, aseries of rounded ribs tapered at both ends secured on said inclinedplane, a vertical Wall secured on said platform and engaging one side ofthe rail, a movable plate engaging the other side thereof and means foradjusting said plate, and means for holding the frog in position,substantially as described.

In testimony Whereof I affix my signature in presence of two Witnesses.

EZRA SMYTI-I.
